- 7 - ABSTRACT (Fig 1) CARTRIDGE FOR A RIBBON FOR TYPEWRITERS The cartridge comprises a container (7) of substantially parallelepipedal form with its corners radiused and rounded off. The container is provided with a back (8) having a slot (27) adapted to guide a slide (26) on the ends of which are mounted and rotatable a feed spool (22) and a take-up spool (32) on which the ribbon (21) is wound. A spring (36) engaged with a stud (41) on the slide keeps the slide (26) towards the right- hand side of the container with the take-up spool (32) engaged with the pin teeth of a feed roller (42). As the turns of ribbon wound on the take-up spool increase, the slide shifts with the two spools towards the left-hand side of the container in opposition to the action of the spring. The cartridge is mounted removably on a support of the machine which is inclined with respect to the horizontal plane of the machine passing through the printing point in a manner such as to permit visibility of the printed characters.
